I speak from experience that once you're in this position he's not stopping until he's finished. It's easier to relax, just try and sit back and enjoy the feeling of a superior man inside you
Oh my God sir fuck my ass. Fuck my white sissy hole and love a good fuck. As long as it's black cock only fuck me and own me use my sissy ass. White pussy is something that you want to blast your load into. You know you're going to want to fuck my white pussy. I can take you deep balls deep inside of me now come and fuck me. Make me your perfect Sissy
Assuming that position means one thing and one thing only. There's no turning back and you're not done until the top says you're done. There's no changing your mind, you can make all the noises you like it only ends one way
